The influence of millennials has been especially pronounced in the retail business. “Their fingerprints are increasingly everywhere,” said Steve Blitz, chief economist at TS Lombard. “Millennials are the first generation in which internet shopping is ingrained in their DNA,” said Blitz, who’s been tracking the spending of baby boomers and millennials. “The 32-year-old is the more aggressive acquire of assets,” Blitz noted. “They are filling up their closets. Baby boomers are emptying theirs.” Blitz says spending on discretionary goods — the things people want to buy — clearly show the shift under way. As millennials become a bigger part of the workforce, sales have risen for restaurants, sporting goods, books, hobby items and home furnishings, among other things. He counsels investors to put their money into the areas where “the wallet share is going.”
